Alright, I am a new user to the Creative Cloud and would like to know which version of photoshop is better. What are the differences between the two verisons? Which should I instal? Etc.
The latest one - CC.
You can install both. Yhey run independently.
There are many differences that range from simple JDI features to major processing and tool changes.
If you havent used Photoshop at all, and that is why you are a new subscriber then of course you can't go wrong with the latest CC version.
